The "Rocker" is the large round button to the left of the screen, which can be rocked or tilted in any of four directions (up, down, left, or right). Sometimes pressing in one direction with too much force can cause another direction to be detected as well; if this happens, try again with less force, or move your finger away from the direction that was incorrectly detected.
